Thanks, I didn't know that.  Given that both OCFS2 and XFS have their
config option for quota, I wonder if it might not be a good idea for
EXT4 to also add a CONFIG_EXT4_QUOTA which selects CONFIG_QUOTA,
CONFIG_QUOTA_TREE, and QFMT_V2.

The alternative would be to have ext4 silently disable support for the
"quota" feature (since the built-in quota inodes have to be V2) if
CONFIG_QFMT_V2 is not selected.

I think the first option is superior; do you agree?
